A program running on a Turing machine can only affect the tape of the machine. The "tape" of a template metaprogram is quite well isolated from other parts of a computer system. (OTOH, templates never cease to surprise...)

Yes, of course (i was jocking :) ) ... ... but probably templates are not so "quite well" isolated from the rest of the computer system, consider an extremely convoluted template that crashes a compiler. Such a crash might be exploitable to run arbitrary code. Certanly it wouldn't be easy and definitelly it would be not portable, but certanly it may happen. (of course compilers may crash not only while handling templates, but this is certanly much more likely ;) ) This is obviously purely accademic, because makefiles or jamfiles are certanly a better place to put malicious code :). -- Giovanni P.
